Introduction

Necessity of Wastewater Treatment

with Bio Septic Tanks in India

India is home to over 1.4 billion people — and with rapid urbanization, the country faces a serious challenge: untreated wastewater pollution. According to the Central Pollution Control Board (CPCB), India generates nearly 72,368 million liters per day (MLD) of sewage, but only 28% is effectively treated. The rest contaminates rivers, lakes, and groundwater — posing major risks to health and the environment.

This growing problem has made bio septic tanks a modern, sustainable necessity for wastewater treatment across residential, commercial, and industrial sectors.

The Wastewater Challenge in India Key Statistics

These statistics highlight a pressing need for localized, low-maintenance wastewater solutions — and that’s where bio septic tanks play a transformative role.

Urban Sewage Generation

India’s urban areas generate about 72,000 MLD of sewage, but existing treatment capacity is only around 20,000 MLD.

What Are Bio Septic Tanks?

Bio septic tanks are eco-friendly sewage treatment systems that use natural bacteria and bio-media technology to break down organic waste into clean, odorless water. Unlike traditional septic tanks, they:

Don’t require frequent desludging.

Prevent groundwater pollution.

Produce treated water suitable for reuse (gardening, flushing, etc.).

Operate without electricity in most cases.

Why Bio Septic Tanks Are the Need of the Hour

1. Environmental Protection

Bio septic tanks prevent harmful effluent from entering soil and water bodies, helping protect rivers like the Ganga, Yamuna, and Cauvery from sewage pollution.

2. Cost-Effective & Low Maintenance

They eliminate the need for large-scale infrastructure, desludging, or chemical treatment — saving both cost and effort for homeowners and industries.

3. Compliance with Pollution Control Board (PCB) Norms

Modern bio septic systems like Nexsa Bio’s are designed to meet PCB-approved effluent standards, ensuring safe disposal or reuse.

4. Ideal for Urban and Rural Areas

Urban: Can be installed in apartments, industries, and institutions where space is limited.
Rural: Provides decentralized wastewater treatment where sewerage systems don’t exist.

5. Supports National Missions

Swachh Bharat Abhiyan – promoting clean sanitation.
Jal Jeevan Mission – ensuring safe water and wastewater reuse.
Smart Cities Mission – encouraging green building infrastructure.

Conclusion

With only a fraction of India’s sewage being treated, bio septic tanks are no longer optional — they are essential. These systems offer a sustainable, cost-effective, and regulatory-compliant way to manage wastewater at the source.

At Nexsa Bio, we are proud to lead this change through RCC and FRP bio septic solutions that help households, industries, and institutions contribute to a cleaner, greener India.
